Abstract

The 10.6μm laser has a wide range of applications in the military field. The various phenomena occurring during the atmospheric transmission of the laser are highly random, and the factors causing the energy dissipation are complex and variable, so it is difficult to obtain an accurate attenuation coefficient. At present, in this field, the research in sunny weather conditions is relatively mature, and the attenuation studies under three special weather conditions of fog, rain and sandstorm are rare. In order to meet the actual needs, this paper derives a simple calculation method for the attenuation coefficient of 10.6μm laser atmospheric transmission on the basis of summarizing the existing research, which can meet certain accuracy requirements in three weather conditions: fog, rain and sandstorm.
